--- Comment #15 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Connor thanks for the detailed bug report too. It was very very useful.
The reason why I changed it to remove the floating point and most of the C++
code was to make it easier to debug. In this case since the `at` method was
important, it was replaced with:
```
if (vertexIdx > t)
__builtin_trap();
```
Which is the most important part of this loop and is part of the reason why it
is miscompiled.
